Face masks could be recommended to protect against dementia in the wake of new research.
Experts have advised the use of masks to filter out dirty air – as well as Covid-19 – following a US study which linked pollution to dementia.
Older people living in areas with a small amount of extra pollution had a 16 per cent higher risk of developing dementia, according to the research from the University of Washington.
The study, of more than 4,000 people over the age of 65, looked at small pollution particles called PM2.5, which tend to come from cars and heavy industry.
